A facile one pot synthetic approach for C3N4-ZnS composite interfaces as heterojunctions for sunlight-induced multifunctional photocatalytic applications

Herein, we report a facile one pot synthetic protocol for the creation of C3N4-ZnS composite interfaces by the co-pyrolysis of a precursor mix containing zinc nitrate, melamine, and thiourea at 550°C in air. The organic-inorganic semiconductor heterojunctions thus formed displayed increased absorbance in the longer wavelength region and facilitated broad absorption of visible light compared to pure ZnS, C3N4 and conventionally synthesized hybrid samples. The decreased emission intensity, increased photocurrent generation and decreased fluorescence lifetime revealed reduced exciton recombinations in the co-pyrolysed sample containing C3N4-ZnS heterostructures. The samples displayed sunlight driven photocatalytic reduction of nitrophenol as well as hydrogen generation (4 mmol g-1 h-1) by water splitting. © The Royal Society of Chemistry 2016

Reactive oxygen species (ROS) mediated enhanced anti-candidal activity of ZnS-ZnO nanocomposites with low inhibitory concentrations

Enhanced antifungal activity against the yeast species Candida albicans, Candida tropicalis and Saccharomyces cerevisiae was displayed by ZnS-ZnO nanocomposites prepared by a simple precipitation technique. The antifungal activity was significantly more in the presence of indoor light than under dark conditions and was a clear confirmation of the inhibitory role of reactive oxygen species (ROS) generated in situ by the photocatalytic nanocomposites. The generation of ROS was further evidenced by flow cytometry results and membrane permeabilisation studies. Time kill assay and growth curve analysis indicated diminished antifungal activity under dark conditions due primarily to Zn2+ efflux in solution. © 2015 The Royal Society of Chemistry

ANALISIS FOLKLOR JEPANG DALAM ANIME GEGEGE NO KITAROU, INUYASHA, DAN NATSUME YUUJINCHOU

Gegege no Kitarou This thesis is a research about Japanese Folklore in anime , Inuyasha and Natsume Yuujinchou. This thesis is a cultural studies that use dynamic structuralism approach. Researcher used dynamic structuralism approach to compare between folklore contained in anime with reality. so many traditions Japan has of folklore that had inherited for generation whether in story form or in tradition form. With some creativity and existing technology that they had, some Japanese filmmaker has succeeded by making some Japanese folklore into more interesting form and well known by people whether inside Japan or outside Japan. Some of them can be found in Japanese animation or can be called anime. Natsume Gegege no Kitarou, Inuyasha and Yuujinchou is the object of this research. These animation was chosen to be the object of this research because first these anime are animes that contained themed Japanese folklore. Second is because these three anime are successful animes and received among fans of Japanese popular culture both in Japan and outside Japan. -m The result of this paper shows that some Japanese film aker has high quality of creativity. With creativity and technology that they had, they can make the almost endangered Japanese folklore into a form that is more attractive and desirable by public, although some are a little different than what is in the reality

PERBANDINGAN VERBA TSUKERU DAN KAKERU

This undergraduate thesis explores and compares two verbs, tsukeru and kakeru. The writer chose these verbs because they can be translated into the same verbs in Indonesian for several same objects, and it became an obstacle for Japanese learners from Indonesia. The writer used three kokugo jiten (encyclopedia of Japanese language), which are Iwanami Kokugo Jiten, Shuueisha Kokugo Jiten, and Kiso Nihongo Jiten to research on the applications of these verbs. The writer used component-of-meaning and case grammar to analyze the similarity and difference of these overlapping applications. The similarity of tsukeru and kakeru A is, if the sentence form is �A o B ni V�, where A (theme) is a liquid, B (goal) is a solid sheet, and V is tsukeru or kakeru as a predicate, the action result will be A covering B. The difference is, if in the sentence form mentioned before, A is a solid and B is a liquid, the result for tsukeru will be a state where A is soaked in B, whereas kakeru will not be able come as a predicate for such sentence. The similarity of tsukeru and kakeru B is that they can be translated into �turn on� in Indonesian if the object is electronic goods or appliances. The difference is the image of the action, where tsukeru express the action of �switch the electronic good from OFF to ON� and kakeru express the action of �doing a job with the help of the electronic good�. The similarity of tsukeru and kakeru C is that they can be translated into �wear, put on� in Indonesian if the object is accessories. The difference is the existence of limitation of object�s shape. No matter the shape, most of accessories can be the object of tsukeru to express the action of �wear, put on�, but only the accessories of which shape are long and narrow that can be the object of kakeru to express the action of �wear, put on�. According to those encyclopedias, tsukeru and kakeru have various applications. Tsukeru is a verb used basically to express the action of �connect two separated things, or connect a thing to a place, and then make them unable to be separated�. Whereas kakeru is a verb used basically to express the action of �connect an unstable thing to other thing which can make them stable�. There are three applications of tsukeru and kakeru which are overlapping each other, which later mentioned as tsukeru and kakeru

Co3O4–C3N4 p–n nano-heterojunctions for the simultaneous degradation of a mixture of pollutants under solar irradiation

Environmental remediation employing sunlight-active semiconductor nano-heterostructures provides effective solutions for handling emerging contaminants through a greener approach. Herein, we report the creation of ultrafine dispersions of Co3O4 nanoparticles in a g-C3N4 matrix by a simple one-pot synthetic strategy involving the co-pyrolysis of constituent raw materials. Calcination of a homogeneous mixture of melamine and cobalt nitrate at 550 °C/2 h leads to the formation of Co3O4-C3N4 p-n nano-heterojunctions that displayed extended absorption in the visible wavelength region owing to the synergistic role of Co3O4 particles. Moreover, the surface area values of the composites reached 90 m2 g-1, a tenfold increase from the value of 8 m2 g-1 obtained for the pristine C3N4. The band bending, induced by the p-n nano-heterojunctions, leads to the formation of intimate interfaces having enhanced photophysical properties. The mass normalized photoluminescence spectra of the heterojunctions indicated reduced exciton recombinations that are validated further by the enhanced sunlight-induced photocatalytic degradation of a mixture of methylene blue and tetracycline organic pollutants

Antifungal properties of nanosized ZnS particles synthesised by sonochemical precipitation

Zinc sulphide (ZnS) nanoparticles, synthesised by a sonochemical route employing zinc chloride and sodium sulphide, displayed significant antifungal properties against the pathogenic yeast Candida albicans (MTCC 227) at a minimum fungicidal concentration of 300 µg ml<sup>-1</sup>. The antifungal properties of zinc sulphide particles is attributed to the generation of reactive oxygen species due to the interaction of the nanoparticles with water. Additionally, the presence of Zn in the zone of inhibition and the absence of antifungal effects for large micron sized particles of ZnS suggest a size induced effect leading to perturbation of fungal cell membranes, resulting in growth inhibition. © The Royal Society of Chemistry
